What should be done if you find an older fan in a radon system that does not meet current Radon Mitigation Standards?

Replacing the older fan in a radon mitigation system that does not meet current Radon Mitigation Standards is essential for ensuring the effectiveness and safety of radon reduction efforts. Older fans may not provide adequate airflow or pressure to effectively mitigate radon levels, which puts occupants at risk if the system fails to perform as needed.

Upgrading the system not only involves replacing the outdated fan but also making any necessary improvements to ensure that the system adheres to the latest standards, which may include checking ductwork, sealing any leaks, and validating that the overall design is appropriate for the specific building characteristics. Once the fan and any other components are updated, recommending retesting of radon levels is crucial to confirm that the new system is functioning correctly and that radon concentrations have been effectively reduced. This comprehensive approach ensures ongoing safety and compliance with regulations regarding indoor air quality and radon exposure, leading to better public health outcomes.
